Ok guys we all have the same problem.I temporarily fix mine by ending the process with task manager twice or thrice and then it doesn't freeze any more until the next system start up.Also today got a few server disconnects.But people this is BETA.Calm your !@#$.I'm sure blizz's on it. :)

I am having the same problem. I start up via the Hearthstone Icon, get a blackscreen with the glove mouse pointer for a short while, and then the spinning rainbow wheel with a black screen. I eventually have to give up and control tab out and it tells me that the program is not responding. Was hoping for some ideas on how to resolve this and actually get to play the game see further than the icon shortcut.

Specific fonts (TTF. files) are interfering with the launch of Hearthstone through the Battle.net Launcher and need to be deleted. Which need to be found by opening the Activity Monitor and starting Hearthstone. It will be marked as "non responsive", then double click on it and hit "Open Files" - scroll till the bottom, till the TTF. files are showing up. Delete the fonts one by one, till the game properly launches again.
